JXE-23 in HCC: Autophagy, Arrest, and Signaling
2026-09-02
A 2024 study identified the fern-derived diterpene JXE-23 as a selective inhibitor of HepG2 hepatocellular carcinoma cell growth, combining G2/M arrest with migration suppression and induction of protective autophagy. Its connection to the CIP2A/p-AKT/c-Myc axis suggests a mechanistic framework for testing JXE-23 and autophagy modulation in anticancer drug research.
